- Compounds of the formula I may be synthesized by reacting 3-methoxybenzylamine and an appropriately selected isothiocyanate compound of the Formula II S ⁇ C ⁇ N—R, wherein R is defined the same as for compounds of Formula I.
- the reaction may be carried out by slowly adding the isothiocyanate to an aqueous solution of 3-methoxybenzylamine, preferably under a nitrogen atmosphere.
- the thiourea product of the reaction which is a compound of formula I, may be recovered and purified by mixing the reaction products with a solvent that is not miscible with water but one that is a solvent for the thiourea, such as methylene chloride, chloroform, toluene or diethyl ether.
- the water layer may or may not be acidified to enhance separation and recovery of the thiourea compound of the invention.
- the thiourea, dissolved in the solvent layer can be drawn off from the water layer, dried and the resulting crude thiourea purified by recrystallization in an appropriate solvent such as ethanol. See, Example 1. See also, generally, the procedure of Moore and Crossley, Organic Synthesis 2, 617–618 (note 4).
- the reactants, 3-methoxybenzylamine and an appropriate isothiocyanate compound as defined above, may be obtained commercially or synthesized by routine methods known in the art, and the resultant product compounds of formula I may be readily isolated by routine methods well-known to those having ordinary skill in the art.
- Suitable isothiocyanate reactants for synthesizing compounds of the present invention may be obtained as well-known in the art from degradation of glucosinolates present in seed oils and other lipids. In an aqueous solution containing the enzyme thioglucosidase, glucosinolate compounds are degraded into isothiocyanates and other degradation products. See, Vaughn, et al., J. Chem. Ecol.
- Glucosinolates pp. 15–30 in M. Rechcigl (ed.) “Naturally Occurring Food Toxicants,” CRC Press, Boca Raton, Fla.
- the isothiocyanate fraction of the glucosinolate breakdown products thus may be isolated and reacted with 3-methoxybenzylamine as described above to provide compounds of the present invention.
- Approximately 100 glucosinolate compounds have been identified in plants from 11 different plant families including mustard, rapeseed, cabbage, garlic mustard and crambe (S. F. Vaughn, 1999.
- Glucosinolates as Natural Pesticides in Biologically Active Natural Products: Agrochemicals, H. G. Cutler and S. J. Cutler, Eds, CRC Press, Boca Raton, Fla.
- Oils isolated from glucosinolate containing plants are normally deodorized by steam sparging to remove volatile compounds which includes isothiocyanates and amines.
- isothiocyanate compounds and benzylamine compounds may be obtained from the waste distillation product generated in the process of purifying such oils and employed as reactants in synthesizing compounds of the present invention.
- 3-methoxybenzylamine may be purchased commercially or may be isolated from meadowfoam oil by extraction into an immiscible acidified aqueous layer which is separated from the oil, washed with a nonpolar solvent, treated with a base to lower pH, and the amine extracted into an immiscible solvent.
- the 3-methoxybenzylamine compound may be further purified by crystallization from ethanol or similar solvent and/or purified by reverse-phase HPLC using a C18 column, eluting with a gradient starting at 100% methanol and proceeding to about 80% methanol:20% chloroform.
- the peak containing 3-methoxybenzylamine may be identified by its retention time on the HPLC column in comparison to the retention time for a known standard sample of 3-methoxybenzylamine.
- Other natural amines may be purchased commercially or may be similarly extracted from natural sources and purified with reference to known standard samples and/or identified by standard chemical methods for identification of amines (e.g., chromatography, infrared spectroscopy, mass spectroscopy, elemental analysis, nuclear magnetic resonance analysis and the like).
- oxidative stability of a lipid may be determined by procedures that are described in the literature. See, for example, K. Tian and P. Dasgupta, Anal. Chem. 71, 1692–98 (1999).
- a presently preferred method of determining oxidative stability of lipids and oils employs the oxidative stability index (OSI), which determines the oxidative stability of an oil by passing air through a sample under stringent temperature control.
- OSI Oxidative Stability Index
- OSI determinations may be performed on a oxidative stability instrument manufactured by Omnion (Rockland, Mass.) using the AOCS method described in the above-disclosed Firestone reference. Lipid or oil samples may be run at 110° C. and FAMEs may be tested at 90° C., with air flow set at 35 kPa with a resulting velocity of about 140 ml/min. A presently preferred method for determining OSI values is described by T. A. Isbell et al., Industrial Crops and Products 9, 115–123 (1999).
- Compounds of the formula I may be conventionally mixed with a suitable lipid or oil and solubilized at concentrations up to 3.0%–5.0% or more. It is presently contemplated that concentrations of a compound of formula I between about 0.1% and 1.0% are sufficient to provide up to about 2-fold to 10-fold enhancement in oxidative stability of a base lipid or oil in need of enhanced oxidative stability. However, lipids or oils of the present invention containing up to 3.0%–5.0% of a compound of formula I are useful as “concentrates” that can be conveniently diluted up to 30- to 50-fold or more with a base lipid in need of enhanced oxidative stability.
- the base composition of such a concentrate may itself be a lipid or oil such as a seed oil or vegetable oil or a food grade solvent.
- a compound of formula I optionally in combination with an amine compound, such as 3-methoxybenzylamine, may be provided in an oil-in-water emulsion or a water-in-oil emulsion, or the like.
- the emulsions are presently contemplated to be especially useful as additives to biodegradable cutting lubricants such as canola oil, soybean oil, vegetable oil estolyte, or other cutting lubricants to enhance the oxidative stability of such lubricants.
- the base lipid or oil is supplemented with an effective amount of a compound of formula I, e.g., a concentration of between about 0.1% and 1.0%, as well as a benzylamine compound present in an amount sufficient to augment the oxidative stability imparted by the compound of formula I.
- a compound of formula I e.g., a concentration of between about 0.1% and 1.0%
- a benzylamine compound present in an amount sufficient to augment the oxidative stability imparted by the compound of formula I.
- the amount of a benzylamine compound to be added to a lipid or oil composition of the invention may be determined by observing increases in OSI values as a function of amount of the benzylamine compound added.
- a base lipid or oil may inherently contain an amine compound
- additional amounts of an amine compound preferably 3-methoxybenzylamine, may be added to a lipid or oil that has been supplemented with a compound of formula I to increase the oxidative stability of such a lipid or oil composition of the present invention.
- the amount of such an amine compound to be added to a lipid or oil composition of the invention to achieve a synergistic anti-oxidation effect may be determined empirically by adding predetermined amounts of the amine compound to aliquots of the lipid or oil composition containing a compound of formula I and measuring the increase in OSI value obtained.
